Nothing will get done if you keep putting it off until tomorrow. You have to do it TODAY eventually so do it TODAY so you can relax tomorrow. Yesterday is already gone, tomorrow may never come but TODAY is the day to do what you need to do so that it gets done. Otherwise you will spend all your TODAY'S wasting your time and energy making plans for how you are going to do it TOMORROW, OVER AND OVER AGAIN. Just do it so you can JUST FLUSH IT OUT OF YOUR MIND. The sooner you get it done, the sooner you can relax because it's done.
